Hi

I have a nonlinear porous drag term in momentum equation which is causing some recilculation at the exit from the porous zone, physical or not, and also some instability. The drag term is essentialy a sink: fvm::Sp(const*mag(U),U). I would like to try to tackle this instability by taking mag(U) from the upwind cell. Is there any provision that would give me for each cell the velocity from an upwind cell?
